SIMON INGERSOLL, OF GREEN POINT, NEW YORK.

IMPROVEMENT IN HAY AND COTTON PRESSES.

Specilication forming part of Letters Patent No. 14,663, dated April l5, 1856.

To all whom, it may concern:

Beit known that I, SIMON INGERsoLL, of Green Point, in the county of Kings and State of New York, have invented a new and Improved Hay and Cotton Press; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which--l Figure l is a longitudinal vertical section of my improvement, the plane of section be' ing through the center. Fig. 2 is a detached vertical section of the levers at one side of the press, showing the wayin which a'n increased power is obtained. j

Similar letters of reference indicate corre- I sponding parts in the two iigures.

My invention consists in operating the follower by means of levers hung in swinging frames and connected to vibrating clamps, which grasp the follower-bars and cause them to be moved upward as the levers are depressed, the clamps during the upward movement oi' the levers being free from the follower-bars, which are secured in proper position by retaining clamps, as will be presently shown and described.

To enable those skilled in the art to fully understand and construct my invention, Iwill proceed to describe it. A

A represents ythe press-box; having a door,

B, at its upper end, and C represents a follower, which is iitted within said box A, the follower being attached to a bar, D, the ends of which pass through slots in the sides of the box A. Each end of the bar Dhas a metallic strap, E, iitted upon it. The upper ends'of these straps are attached by pivots or joints to the lower ends of vertical bars F. The lower ends of the bars F are bent for a short distance horizontally, the straps being at-v ends of the levers are each attached to a vibrating clamp, I. These clamps are formed of two bars, M, connected by rods c c, between which the follower-bars F F pass. The inner ends of the bars M of the clamps rest upon ledges or projections N, attached to the sides of the press-box.

O Oare links, which are hung on rods (1 chains or ropes f are attached.

The operation of the press will be readily understood. The press-box is iilled with the material to be pressed, the follower C being at the bottom of the press-box. The door B is then closed and secured in any proper manner. The outer ends of the levers H are then depressed, and the inner ends of said levers will be forced or turned upward, causing the rods c c of the clamps I to bind or grasp the rods F, and causing said rods to 'be elevated. When the outer `ends of the levers H are elevated, to be again depressed, the rods c c do not bind or grasp the rod, but the rods are retained by the clamps P. By this means the follower C is raised and the article in the press-box compressed. At the commencement of the operation the levers H are worked 4 v in nearly or quite a horizontal position, or a horizontal position may be considered asthe central points of their stroke or vibration in order to obtain speed, as much power is not required at first; but as the material becomes somewhat compressed an increase of power is required, and the levers H are then worked in amore oblique or inclined position,as shown in Fig. 2. By this means the lower ends of the swinging frames G G are thrown inward or toward the press-box A, and the rods .1), which are the fulcra of the levers H, are consequently brought nearer the weight to be overcome, or nearer the points of attachment of the levers H to the clamps I, and consequently the power will be increased and the speed correspondently diminished.'

When the article within the press-box is fully compressed and bound, it is removed therefrom, and the follower C is allowed to descend to the bottom of the press-box by pulling the chains f, which will cause the inner ends of the retaining-clamps P to be elevated,

' and the rods e e to release their hold of the the retaining-clamps I or their equivalents follower-bars F F. being,` employed for sustaining or holding the Having thus described my invention, what follower when the bars F are released from I claim as new, and desire to secure by Letters the clamps I, substantially as shown and de- Patent, isscribed.
